1. An electronic device comprising:
processing circuitry configured to be coupled to a touch sensor panel, wherein the processing circuitry is configured to:
obtain first touch data from the touch sensor panel at a first time interval, including receiving a first touch image from the touch sensor panel, the first touch image captured concurrently with an updating of a display in proximity to the touch sensor panel;
obtain second touch data from the touch sensor panel at a second time interval, different from the first time interval, including receiving a second touch image from the touch sensor panel, the second touch image captured concurrently with a blanking the display; and
generate third touch data, wherein generating the third touch data includes removing noise from the first touch data using at least a portion of the first touch data and at least a portion of the second touch data.
